Why 310 of Robinhood's 7 Million Cyber-Attack Victims Should Be Really Quite Worried

Robinhood Markets Inc. announced on Monday an embarrassing security breach that exposed the personal information of millions of its users, which will be of particular concern to the 300 or so customers who suffered the worst privacy compromise.

Most of the 7 million affected accounts had only one piece of personal information exposed: either the user’s name or their email address. But in about 310 cases, more sensitive data such as date of birth and zip code was uncovered, as well as the user’s full name. About 10 of those people had “more extensive account details revealed,” Robinhood said, adding that the company is in the process of “making appropriate disclosures” to those users.
